Lately I've been getting these errors trying to install updates. The "automatic troubleshooter" just seems to reset the updates database to null and give me a green light. The updates still won't install. I searched around and found KB947821, downloaded Windows6.1-KB947821-v25-x64.msu, and ran it. It ran successfully but it doesn't help. I also turned off my security suite (Norton) but that doesn't help either. I did more searching around but I'm getting nowhere with this problem. Thank you for any assistance.

You have a total of 105 errors showing in the CheckSUR log - and I should imagine that there are going to be more problems, in view of your failures, as the regstry is very likely impacted as well.
I would favour a repair install as the proper way to go here.
First, please ensure that the filesystem is in a reasonable state - Tom may like to take on the challenge, even if I don't

Please run a full CHKDSK and SFC scan....

Click on Start > All Programs > AccessoriesRight-click on the Command Prompt entrySelect Run as Administrator and accept the UAC prompt - the Elevated Command Prompt window should pop up.

At the Command prompt, type

CHKDSK C: /R

and hit the Enter key.You will be told that the drive is locked, and the CHKDSK will run at he next boot - hit the Y key, and then reboot.

The CHKDSK will take a few hours depending on the size of the drive, so be patient!

After the CHKDSK has run, Windows should boot normally (possibly after a second auto-reboot) - then run the SFC.

It bothers me that when I click on "Update History" in Windows Update, the only history that shows is after I ran Microsoft's "troubleshooter." I think the troubleshooter just wipes out some databases so you can start afresh. Not even KB947821 is showing in the history; it did before.

Run it - The tool can take anywhere from 5 mins to a couple of hours to run (or 'Install') depending on how much it has to do, and may exit silently - it may appear to freeze for most of that time, but be patient.The result is logged in the C:\Windows\Logs\CBS\CheckSUR.log file - and an archive …\checksur.persist.log file

I was hoping that something would have changed - but apparently it was not to be
The question now is whether this is within the realms of viability for a manual fix or not, as there's a distinct possibility of further problems showing up when/if we do manage to fix these.

If you *really* want to avoid a repair install, then I can try to fix these, and see what happens - otherwise, I do think that the repair is the way to go.

Go on, let's give a fix a go! 6 updates is a lot to fix though! This is probably the worst 80B0100 log I've ever seen before.
